We test a few times a week. If you post an NCP, chances are, it will be reviewed in the next 4-5 days. We are not superhumans, so please don't expect a response within an unreasonable amount of time. And, rest assured, we keep close track of all the variants we need to review.
List of things the CGAs are working on.

not NCPs new settings or peices
Don't you think we already have enough fairy pieces?
(Additionally, new pieces require lots and lots of code- not the responsibility of CGA's)😉

how to apply???? or was it just that thing between 2019 and 2021?????
There's no set application process, sorry.

I'm confused as to what "thing between 2019 and 2021" you're referring to.
As for how I got in, you have to be asked to join (they asked me, I said yes).

no i just want a list of the things that this article https://www.chess.com/clubs/forum/view/any-plans-for-more-settings-like-the-2-player-variants askes if people are working on and i don't know why i said CGAs but i just mean - whoever is in charge around were.
Because there is like everyday a forum asking "are the CGAs doing this" "are the CGAs making that"
I suggest that the CGAs post a locked and pinned topic on which varients new pieces new rules..... they are working one/testing and possibly an expected date of arrival?
+1 or -1
